CHARGING A ND DRAWING APPARATUS FOR HEATING-FURNACES.

SPECIFICATION forming part of Letters Patent N 0. 646,475, dated April3, 1900.

Application filed August 29, 1899. Serial No. 728,855. (No model.)

To aZZ whom it may concern.-

Be it known that I, JARED SWANGER, 'residing at Chester, in the countyof Delaware and State of Pennsylvania, have invented certain new anduseful Improvements in Charging and Drawing Apparatus forIiIeating-Furnaces, of which the following is a specification.

My invention relates to apparatus for carrying the piles or slabs ofiron required to be charged and drawn in the operations ofheating-furnaces. Its primary objects are to avoid carrying thepeel-supporting mechanism over the tops of-the furnaces, to provide astable and readily-adjustable support for the peel, to provide meansthrough which the load may be carried by gravity both in charging anddrawing, and to secure universal motion in the operation of the peel.

In the accompanying drawings, Figure'l is a side elevation illustratingmy invention.

Fig. 2 is a sectional view on the line A,il1ustrating a detail. Fig. 3is a sectional View on thedine A, illustrating a detail. Fig. 4 is asectional view on the line a, illustrating the connection between thepeel and the supporting-lever. Fig. 5 is a sideelevation, partially insection, showing a detail of the supporting-lever; and Fig, 6 is a sideelevation illustrating a modification in the construction of thecarrying-bar.

Referring to the drawings, the peel 1 is supported by a substantiallyZ-shaped lever or carrying-bar 2, the peel-being suspended from the endof the'lever-arm 3 by a hook 4, which passes freely through and isswiveled in an aperture 5 in the arm, a collar 6 being formed on thepeel to prevent it from moving longitudinally through its bearing. Thelever 2 is supported byahanger 7, to which it is pivoted, and by a strut8, which engages in adj ustable relation with the rearwardly-projcctinglever-arm 9, as by passing a bolt through the arm and the strut,permitting the height of the arm 3 and the peel 1 to be varied. Thehanger 7 depends from a truck 10, the wheels 11 of which straddle theI-bar 12 and run upon the inner faces of the flanges 12' thereof. Thestrut 8 depends from a truck 13, the wheels 14 of which are flanged, soas to straddle and run upon the outer faces of the I-bar flanges 12.

The I-bar, forming the track for the trucks,

the long arm of the peel.

is suspended at one end by the rod 15 and at the other end by the rod16. In order to adjust the track to the inclinations required for bothcharging and drawing by gravity, one of the suspended rods, as 16, isalternately elevated and lowered, as may be required. This may beaccomplished by providing the rod 16 with a rack 17, which is engaged bya gear wheel 18, against which it is held by a roller 19, journaled in afixed support. A second gear-wheel 20 is fixed to the gear-wheel 18 andis engaged by the worm 21, which is driven by a sprocket 22 and chain23,connected therewith. This mechanism is supported by a beam 24, which,if desired, may be a member of a traveling crane, by which themechanismmay be moved into position for charging and drawing any one ofa series of furnaces. To sustain the pile upon the peel, a strut 26 ishinged to the Z-lever and when allowed to fall straddles the peel andtakes the upward thrnstfrom It will be evident that by squaring thepeel-rod at the point where it is straddled by the strut the strut willserve to prevent the peel from turning in its bearing when down.

In the construction illustrated in Fig. 6 the carrying-bar is formed intwo parts to effect the adjustment of the arm 3, which carries the peel,to various heights. A member 2 extends upward from the arm 3 and hassecured thereto the straps or keepers 30 and 31, through which runs themember 2, depending from the arm 9. The part 2 is provided with holes32, through which and the strap 31 a pin 33 is passed to hold the arm .3atthe desired elevation. Pins or studs 34 and 35 on the respective parts2 and 2, with the lever 36, provide means for elevating andlowering thearm 3 when the pin 33 is withdrawn, at stop 37 limiting the downwardmovement of the arm. The lever is sustained by a hanger 7 and a truck 10(illustrated in end elevation in Fig. 2) and by a truck 13, bearing uponthe eyebar or track 12, asillustrated in Fig. 3.

From the foregoing description it will appear thata pile upon the peelmay be shifted about at will by means of the universal motion permittedby its connection with the Z-lever,

and the peel-supporting arm may be adjusted reason of the heat andweight to which it is subjected the peel becomes bent, it can berevolved in its seat or journal in the hook to the reverse position andbrought back to its original shape by use. When it is desired to chargeor draw, the worm-gear is operated so as to give the requiredinclination to the I- beam forming the track upon which gravity carriesthe load in the desired direction, the worm and gear then holding thetrack in any position to which it may be moved.

Having described my invention, I claim 1. In a furnace charging anddrawing apparatus, a track, a carrying-bar suspended from said track,said bar having a substantiallyvertical member, an upper arm extendingaway from the furnace and connected with said track and a loweroppositely-extending arm for entering the furnace, in combination with apeel having a swiveled connection with said lower arm.

2'. In a fn rnace charging and drawing apparatus, a track, means forvarying the inclination of said track, a carrying-bar suspended fromsaid track, said bar having a substantially-vertical member, an upperarm extending away from the furnace through which said bar is connectedwith said track and a lower oppositely-extending arm which enters thefurnace, in combination with a peel having a swiveled connection withsaid lower arm.

3. In a charging and drawing apparatus, a carrying-bar having asubstantially-vertical member, a forwardly-projecting arm and arearwardly-projecting arm, a hook swiveled in said forwardly-projectingarm, in combination with a peel journaled in said hook, a hanger forsupporting said carrying-bar, and astrut for sustaining saidrearwardly-projecting arm, substantially as specified.

t. In a furnace chargingand drawing apparatus, a track comprising asuspended eyebar, a truck which straddles said eyebar and rides upon theflanges thereof, a hanger supported by said truck, a carrying-barsuspended from having an upper arm extending away from the furnace forsupporting said bar, and a lower oppositely-extending arm for enteringthe furnace, a peel supported by said lower arm and a track forsupporting said upper arm.

6. In a furnace charging and drawing apparatus, a track, a carrying-bardepending from said track having an arm extending away from the furnaceand connected with said track and a substantially-vertical arm, a secondcarrying-bar having a substantially-vertical arm movable along saidfirst vertical arm in adjustable relation and an arm which extends in'tothe furnace, in combination with a peel supported by the arm whichextends into thefurnace.

7. In a furnace charging and drawing apparatus, a carrying-bar having asubstantiallyvertical member, an upper arm extending away from thefurnace and a loweroppositelyextending arm which enters the furnace, incombination with a peel supported by said lower arm, and means foradjusting or varying the elevation of said bar, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JARED Sl/VANGER.
